Calvin Klein's "Obsession" (buy the big bottle)
assorted organic chemicals common in perfumery (will be provided by instructor)
your lab notebook
pen or pencil
10-mL graduated cylinder
test tube (7-10 mL)
1) Measure 10 mL of "Obsession" into the graduated cylinder and transfer this to the beaker.
2) According to your whim, add chemicals from the organics cabinet to the test tube, dropwise, carefully recording in your notebook which compounds you used, and in what amount. Stir after each drop added
3) When you have come up with a fragrance you dislike, add it to the sample of "Obsession" in the beaker and stir with the stir rod.
4) You should now have a mixture which smells like neither the "Obsession" you began with or the unpleasant-smelling assemblage from the test tube.
a) If the resulting mixture is not an improvement on the original "Obsession" sample, discard it, wash all glassware (including the stirring rod!), and begin again from step 1.
b) If the resulting mixture is an improvement on the "Obsession" you began with, contact Calvin Klein's perfume people about marketing your mixture as an adjunct fragrance called "Compulsion," for exclusive use by people who are already wearing "Obsession."
The first student (or if you have a lab partner, pair of students) to have a signed agreement with Calvin Klein will receive an A for the course. All other students will fail and must repeat the class during the summer session.
